The identifiable 'accent' associated with a particular telegraph operator. According to Neal Stephenson's Cryptonomicon, the patterns associated with individual operaters are sufficiently unique that it is possible to recognize them fairly accurately (and also to fake them).

A fighting style--possibly a bad translation from Asian-language martial arts movies. I recall hearing it used this way in Fist of Legend--as a Westerner with no martial arts experience, it seems odd to me to break down how one fights into different sets of moves. Particularly when a single person knows several fists, it was initially baffling that s/he wouldn't simply learn a bunch of stuff and use whatever made the most sense at the time--rather, the characters seemed to decide on a fist, and then use it until there was a conscious decision to change fists. I've been trying to explain it to myself, and it seems as though there might be stances associated with particular moves, as well as sets of moves that chain well--since you really DO need to make a conscious decision to adopt a particular stance, you're already committing yourself to one set of moves or another at that point.

Small addendum to kelrin's writeup: As in telegraphy, "fist" is used in amateur radio jargon to refer to a CW operator's transmitting style, or to refer to an operator's ability to transmit CW with skill and clarity. An operator who sends well-formed dits and dahs, properly spaces characters, and makes a minimum number of errors is said to have a good fist; an operator who is clumsy in timing dits and dahs or who makes lots of errors is said to have a sloppy fist. (I swear I am not making this up.)
